Bugs

#153538

Advisory

https://security.gentoo.org/glsa/200812-15

Affected packages

Package	Arch	Vulnerable	Unaffected
media-gfx/povray	*	< 3.6.1-r4	>= 3.6.1-r4

Background

POV-Ray is a well known open-source ray tracer.

Description

POV-Ray uses a statically linked copy of libpng to view and output PNG files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964, CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in POV-Ray's build system caused it to load the old version when your installed copy of libpng was >=media-libs/libpng-1.2.10.

Impact

An attacker could entice a user to load a specially crafted PNG file as a texture, resulting in the execution of arbitrary code with the permissions of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All POV-Ray users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4"
